assmuon r0 nmacrnomr'nc PBODUOTS CO A CORPORATION OF NEW JERSEY. METHOD OF ASSEMBLING RADIATOR-SECTIONS.

Toall whom it may concern I Be it known that I, FREDERICK A. FELD- KAMP, a citizen of the United States, residing at Newark, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in Methods of Assembling Radiator-Sections; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being bad to the accompanying drawings, and to characters of reference marked thereon, specification.

This invention has reference, generally, to a. novel method of assembling a plurality of radiator-sections or cooling units and securing them in their assembled relation by means of the connecting strips of the general character and construction set forth in my previous application for Letters-Patent, filed September 27, 1912, Serial Number 722,663.

The present invention, therefore, has for its principal object to provide a novel method or process of primarily assembling, a; plurality of thin and hollow radiator-secwhich form a part of this home over an arrangement of narrow strips,

preferably with U-shaped portions, disposed of grooves or channels therefor and formed in a plate-like body or bodies, then placing the narrow edge-portions of the radiatorsections down upon and within said U- shaped portions of the said strips in the said grooves or channels of said body or bodies,

in a series securing the parts in their assembled rela-' tions, and finally dipping the perforated and grooved plate, with the said narrow strips and the radiator-sections, in the manner hereinafter stated, in a soldering or tinning solution, in order that at one time all of the U-shaped portions of the connectthe novel process or ing strips will be solidly united with the marginal edge-portions of the plurality of radiator-sections or cooling units.

VVit-h the various objects of the present invention in view, the invention consists in method for connecting or securing the connecting strips or wires to the marginal edge-portions of a plurality of radiator-sections.

The invention is clearly illustrated in 65 the accompanying drawings, in which Specification 01' Letters Patent. Application filed November 5, 1912.

Figure 1 is a forated and with the plan view of a strips or wires arranged in position grooves of the said plates, said view' showing in connection with the said plates, diagrammatically, a fluting roll, apair of guide-bars, and an arrangement of knives for severing the strips or wires after having een arranged in the grooves or channels of the plates. Fig. 2 IS an enlarged plan view of one of the said perforated and grooved plates with the narrow stripsor. wires in place, showing in plan view upon said plate an assembling frame and a number of the radiator-sections held in their assembled relation upon the by the said assembling frame. Fig. 3 is a transverse vertical section, taken on line 3-3 in said Fig. 2; and F ig. 4 is a vertical cross-section, taken on line 4 -1 in said Fig. 2, looking in the direction of the. arrow w. Fig. 5 is taken on line 55 in said Fig. 1, said View being made on an enlarged scale, and shdwing in connection therewith a holding bar for retaining the narrow strips or wires in the grooves or channels of the plate. Fig. 6 is an elevation of the holding bar removed from the plate; and Fig. 7 is an enlarged end view of the same. Fig.8 is a front elevation of the retaining frame shown in said Figs. 2 and 3, removed from" the perforated and grooved or channeled plate. Fig. 9 is a front elevation of the two perforated and grooved or channeled plates with the devices therebetween in their connected and assembled relations, ready for the dipping step of the process.

Similar characters of reference are employed in all of the above described views, to indicate corresponding parts.

In carrying out the several steps of the novel method or process of securing b means of soldering or by the'tinning metho the narrow strips or wires units of the radiator, the apparatus illustrated in the several figures of the drawings is employed. This apparatusconsists, essentially, of two plates 1 and 2, the plate 1 being formed with suitably formed ears or lugs 3, each of which is provided with an upwardly projecting dowel-pin 4. The plate 2 is likewise formed wit-h correspondingly located ears or lugs 5, each ear or lug 5 having a hole or perforation 6, into and grooved plate.

to the hollow pair of per- I grooved or channeled plates a vertical cross-section,

the

through which holes or perforations the screw-threaded end-portions 7 of the dowelpins 4 are assed, and'are adapted to receive suitab e nuts 8 for securing the parts in their assembled relations, substantially as illustrated in Fig. 9 of the drawings and for the purposes hereinafter more fully specified. The said ears or lugs 5 of the plate 2 are also provided with dowel-receiving holes or perforations 9.

As will be seen from an inspection of Fig. 1 of the drawings, the plate 1 is made with a series of parallel and laterally extending grooves or channels, as 10, the-sides of which taper substantially in the manner shown, so that each channel is wider at and across the top than across the bottom, 11 indicates a series of narrow strip or wirereceivinv grooves or channels which extend longitudinally across the upper surface of late 1, and cross the said laterally exor channels 10 in the mantendlng grooves At the several crossings of ner illustrated. said grooves or body of the plate 1 is provided with aplurality of holes or openings, as 12, the diameter of each hole or opening 12 preferably being equal to the distance across the widest partof each roove orchannel 10, as will be clearly evident from an inspection of Figs. 1, 2, 3 and 4 of the drawings. grooves or channels 10 are also made much deeper than the grooves or channels 11, for the proper arrangement of the narrow strips or wires 13 and their U-shaped parts 14 in the respective channels or grooves, as will be clearly understood from an inspection of Fi 3 of the drawings.

Re erring now once more to Fig. 1 of the drawings, it will be seen that the plate 2 is also made with a series of parallel and laterally extending grooves or channels 15, the sides of which also taper substantially in the manner shown, sov that each channel is wider across the top than across the bottom, and 16 indicates a series of narrow strip or Wire'receiving grooves or channels which extend longitudinally across the upper surface of the plate 2, and across the said laterally extending grooves or channels 15 in the manner shown.- crossings of said grooves or channels 15 and 16, the body of the plate 2 is provided with a plurality of holes or openings 17, the diameter of each hole or opening 17 preferably being equal to the distance across the widest part of each groove or channel 15. The grooves or channels 15 are also made much deeper than the grooves or channels 16, for the proper arrangement of the narrow strips or wires 13 and their U-shaped parts 14 in the respective channels or grooves. The said plate 2 is also provided with a pair of rforated ears or lugs18, with which are suitably connected, by means of nuts 19, a

and

channels 10 and 11, the.

The

At the several" novvgoaa pair of rod-like elements or members, as 20, which are bent, as at 21, to provide suitable handles or lifting means for raising and reversing the plate 2 from its position indicated in Fig. 1 of the drawings to that represented in said Fig-S), and for the purposes of suspending and properly handling the two connected plates 1 and 2 during the dipping steps of the soldering or tinning process.

In carrying out the different steps of the process, the two plates 1 and 2 are arranged end to end, preferably as shown in said Fig. 1, with a slight space 22 between said plates, and a suitable cutter or severing means 23,

located above said space and adapted toenter the same. At the other end of said plate 1 is suitably located another cutter or severing means 21, a pair of suitably formed and perforated strip or wire-guides, as 25 and 26, and a fiuting means 27 for provid ing the strips or wires 13 with the previously-mentioned and properly distanced U-shaped parts 14. The said cutters or severing means '23 and 24, the said guides 25 and 26, and the fluting means 27, are merely diagrammatically represented, and these devices may be of any suitable and wellknown construction. The various devices and parts having been arranged in this manner, the narrow strips or wires 13 are first drawn through the perforated uide 25, and passed into and through the uting means 27 where the strips or wires 13 are provided with the equally distanced U-shaped portions 14. The strips or wires 13 are then drawn through the perforated guide 26, and located in the alined'grooves or channels 11 and 16 of the respective plates 1 and 2, with the U-shaped portions 14: of the strips or wires 13 located in and extending downwardly into the deeper grooves or channels '10 and 15 of the respective plates 1 and 2,

at the crossing of the said grooves or channels 10 and 15 with the respective grooves 11 and 16, so that the said U-shaped portions 14: of the strips or wires 13 will be variously located in the holes or openings 12 of the plate 1 and the holes or openings 17 in the said plate 2, and will extend diametrically across the said openings, as will be clearly evident from an inspection of the several figures of the drawings. The desired number of narrow strips or wires 13 having thus been arranged in the several grooves or channels of the two plates 1 and 2, the cutters or severing means 23 and 24 are suitably operated, so that the said strips or wires are cut into short lengths, and that each plate 1 and 2 will be independently provided in its grooves or channels with a plurality of such strips or wires 13. That the said strips or wires 13 may be properly held and retained in the various grooves or channels of the plate during the cutting or severing step, and also during the following steps of the process, an open metal frame, as 28, is placed over the strips or wires 13 in the grooves or channels in the plate 1, the frame 28 serving also another purpose for properly spacing and retaining the radiator-sections or units 29 vertically in alinement with the respective laterally extending grooves or channels 10 of said plate 1. For the same reason, that the narrow strips or wires 13 are properly held and retained in the various grooves or channels of the plate 2, during the cutting or severing step, and also during the following steps of the process, a .pair of holding bars 30 are arranged across the strips or wires 13 and the respective ends of the plate 2, said bars 30 being provided at their endportions with split pins or dowels 31, which are forced into holding engagement with the holes or perforations 9 of the ears or lugs 5 of the said plate 2, as will be clearly understood from an inspection of Fig. 5 of the drawings. The frame 28 having been placed upon the grooved or channeled sur face of the plate 1, the desired number of radiator-sections or units 29, to the man ginal edge-portions of which the said narrow strips or wires 13 are to be secured by soldering or by the tinning process, are then inserted in suitably spaced cut-away or grooved portions 32, as shown in Fig. 2 of the drawings, with the marginal edgeportions 33 of the said radiator-sections or units arranged in the laterally extending grooves or channels 10 of the plate 1, and resting directly in the U-shaped portions 11 of the said strips or wires 13, as indicated in'Fig. 3 of the drawings. The plate 2, with the series of narrowstrips or wires 13 arranged and held in the various grooves or channels of said plate, in the manner hereinabove stated, is now raisedby means, of the handles or lifting devices '21, and brought into its inverted position over the marginal edge-portions 34 of the radiatorsections or units 29 held by means of the frame 28 upon the plate 1. Upon the lowering of the plate 2, the edge-portions 34 of the said radiator-sections or units 29 enter the laterally extending grooves or channels 15 in said plate 2, said edge-portions resting also directly in the U-shaped portions 1-1; of the narrow strips or wires 13 which are located in the channels or groovs 16 of the said plate 2, as will be clearly evident from an inspection of Fig 9. At the same time, the previously-mentioned dowelpins 4 of the lugs or ears 3 of the plate 1 enter the holes or perforations 6 in the lugs or ears 5 of the plate 2, and by means of the nuts 8 which are screwed upon the'projcctingeuds of the said pins 4, the various' eandparts are securely maintained i in their assembled relations, readyjfgf the dipping steps of the process. The bottom of the plate 1 is new dipped. or placed for a short time in a bath of fluid solder or liquid tinning material to such depth that the fluid will fillthe holes or perforations 12 in the plate ,1',and that the U-shaped portions 14 of the strips or wires 13, and the exposed edge-portions of the radiator-sections or units 29 will also become immersed in the liquid solder or tinning fluid. Upon the removal of the plate 1 from the bath, sufficient liquid solder or tinning fluid will adhere to the'U-shapedportions 14 and the edge-portions of the radiator-sections or units, which immediately solidifies and causes the said parts to be securely and positively united, as will be clearly understood. The devices and parts .-in their assembled positions, indicated in said Fig. 9 of the drawings, are now reversed, and the bottom of the plate 2 is then dipped or placed for a short time in the bath of fluid.- solder or liquid tinning material, and to such a depth that the fluid will fill the holes or perforations 17 in the plate2, and that the U-shaped portions 14: of the strips or wires-13, and the exposed edge-portions of the radiator-sections or units 29 will also b'ecdme immersed in the liquid solder or tinning fluid. Upon the removal of the plate 2 from the bath, suflicient liquid solder or tinning fluid will also adhere'to the U- shaped portions 14: and the edge-portions of the radiator-sections or units, which immediately solidifies and causes thesaidparts to be securely and positively united, as will be evident. Upon removing the nuts 8 from the pins 4, the plate 2 can be taken away, and a complete radiator consisting of a plurality of equally spaced radiator-sections or units, securely connected at theirv front and rear marginal edge-portions by means of the narrow strips or wires 14, is the result, which is easily removed from the plate 1 and the frame 28.

From the foregoing description of the present invention, it will be seen, that I have provided a novel method for simulta-' neously securing, by soldering or by the tinning process, a great many strips or wires to the marginal edges of a plurality of radiator-sections or units, thus greatly minimizing the labor in assembling the parts, and materially reducing the cost of manufacture.
